what is the range of the function f(x)=12-3x for the domain {-4,-2,0,2,4}?

a. {24,18,12,6,20}
b. {6,12,18,24,30}
c. {-12,-6,0,6,12}
d. {0,6,12,18,24}

Range us {0, 6, 12, 18, 24}.

Step-by-step explanation:

The range of a function is the output values after inputting the domain.

To find these, substitute the values of the domain.

f(x)=12-3x

f(-4) = 12 - 3(-4) = 12 + 12 = 24

f(-2) = 12 -3(-2) = 12 + 6 = 18

f(0) = 12 -3(0) = 12-0 = 12

f(2) = 12 -3(2) = 12-6 = 6

f(4) = 12 -3(4) = 12-12 = 0

The range is {0, 6, 12, 18, 24}.

answer: plz put a pic in so i can answer it

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
